I know nothing about these engines but I put 1p37QMA-2 in a google search and see a big bore kit -Naraku Big Bore Kit for SYM 1P37QMA $109.97-it looks like all the parts are available, they are just harder to find. I'm guessing most everything else applies ... a little bigger jet, free flowing exhaust, maybe a restricter spacer in the variator, CDI rpm limiter, free flow air cleaner.
